Definitions

  • the invention relates to an operating device to control and drive a closing and/or locking mechanism of a door, window, panel or the like, in particular of the manually operable type.
  • the majority of doors will be closed, opened, locked and unlocked by a closing and locking mechanism - where a jamb prevents the door from swinging to both sides and the locking and blocking mechanism is fitted in an end face of the door, controlling the engagement and disengagement between the door and the jamb of the door.
  • FIG. 1 An example of these common closing and locking mechanisms, also referred to as door locks is shown in fig. 1 , and there has been given the reference numeral (16).
  • the mechanism can be fitted in the end face of the door and are driven by radial
  • the internal mechanism of the closing and locking mechanism contains a return spring connected to the latch bolt that also operates the door handle. So if the handle is released by hand after applying, the handle and the latch bolt (21) return to the original position.
  • the closing and locking mechanism doesn't provide an automatic return as the locker-indicator needs to stay in closed mode, and a specific manual action is required to operate the dead bolt (20).
  • Door handles are usually rotated by bare hand, and in a next stage the door is opened or closed.
  • Toilet locker-indicators are usually small grips and the required torque for the radial movement/rotation can be high, especially for those who are less capable like disabled, children and elderly people.
  • These handles and locker-indicators are applied by bare fingers and hand, and as is well known, in public areas bacteria and infections are easily passed, transferred and spread by use of these handles and locker-indicators.
  • a disadvantage with those known solutions is that they have rather complex and/or vulnerable constructions, which may be expensive to manufacture.
  • the locker-indicators are then still to be applied by bare fingers and hand, and bacteria and infections are easily passed, transferred and spread by them.
  • the present invention aims to at least partly overcome one or more of the above disadvantages or to provide a usable alternative.
  • the invention aims to provide a user-friendly and cost-efficient operating device with which doors, windows, panels and the like can be opened and locked in a hygienic manner.
  • the operating device comprises a manually operable pusher and a rotator.
  • the rotator has a provision for connection with a closing and/or locking mechanism, in particular for connection to an axle of a common type of closing and/or locking mechanism as described above.
  • a translation-to- rotation mechanism is provided between the pusher and the rotator such that a translational movement of the pusher in an axial direction results in a rotational movement of the rotator around said axial direction.
  • a first spring is positioned in the axial direction between the pusher and the rotator.
  • a two-position switch locking mechanism is provided in between the pusher and the rotator.
  • the two-position switch locking mechanism is designed to provide for an outer release position of the pusher relative to the rotator, and for an inner blocking position of the pusher relative to the rotator. A switching from the outer release position towards the inner blocking positions is
  • the first spring acts as energy buffer which stores energy the first time the pusher is pushed inwards and which releases this energy again after the pusher has been pushed inwards the second time and then has been released again.
  • the invention provides a device that drives, rotates and controls an axle of a closing and/or locking mechanism by applying a small linear load to, for example locks for doors, windows, panels, toilets, and emergency exits.
  • the device controls the lock to open, close, unlock and secure instead of the usual rotation of a handle, grip or the like.
  • the device converts a linear movement into a radial movement.
  • the device includes a holding mechanism and self-driven return mechanism.
  • the invention includes a spring, to force the device back into the top position holding the mutual axle in relative position to the device.
  • the device also includes an internal blocking/unblocking mechanism (the two- position switch locking mechanism) that holds the mutual axle in a different radial position. These positions of the device /axle correspond with a latch bolt and/or dead bolt to secure a door, window or panel in an open or locked position.
  • the axle rotates, forcing the device into the inner blocked position preventing further axle rotation.
  • the internal blocking/unblocking mechanism can be released by a small push on the knob and the spring drives and resets the device and the door mechanism back into the top position, rotating the axle in the same action, in the opposite direction.
  • the axial load needed to operate the device - as a push action is required - can be done with the fingers, hand, hand palm, elbow: basically anything or any tool or instrument.
  • the benefit is that the often difficult rotation of most common handles, and the actual use of the fingers and hand can be avoided, by pushing the knob with, for example, the elbow or forearm.
  • a small push is enough to let the spring of the device take over the action. Therefore, the only manual action required to open, close, lock, unlock or secure is a push on the knob of the device.
  • the use of bare fingers for operating a toilet lock is no longer required so that the spreading, transferring and passing of bacteria and infections can be reduced. This is of great importance for health in general and is particularly important in hospitals where the spread of infection can have severe consequences for those with low immune systems.
  • the door handle and the knob can then be operated by one hand using the thumb for the knob of the device and the rest of the hand to operate the door handle. This will be of great benefit for those situations where extra stability is required. Examples include elderly and disabled people and ship and trains.
  • the device can be set to positioning the latch or dead bolt in either a locked or unlocked position.
  • the translation-to-rotation mechanism comprises a worm bushing with a worm groove and a matching worm of a worm shaft, positioned in the same axial direction, wherein the worm bushing is restricted to move radial relative to the worm shaft, and wherein the worm shaft is restricted to move axial relative to the worm bushing, or vice versa.
  • the mating worm and worm groove rotates the other one of the worm bushing and worm shaft.
  • the first spring in this embodiment is positioned in axial direction between the worm bushing and the worm shaft to force the worm shaft away.
  • the locking mechanism comprises a rotor with inclined surfaces on splines, mating with inclined surfaces of teeth of the pusher in the same axial direction.
  • the connected rotator for example the worm shaft
  • the connected rotator is forced to rotate, and can rotate, forcing the worm bushing by pulling towards the lock, or - when the internal friction is different - the worm shaft rotates and the starts of the worm shaft slide into the grooves of the worm bushing, or a combination of these two actions.
  • the door can be therefore opened from the outside easily and the device won't be damaged.
  • an indication or marking is provided on the pusher or onto a cover of the pusher. This allows the user of the device to recognise whether the device is in the locked or unlocked mode. If the marking is positioned on a lower part of the pusher or cover , it will not be visible when the device is in an inner blocked position but will be visible in a top position. Therefore there can be no confusion, unlike the case with current door handles where there is no visible difference on the handle itself.
  • a colour such as white, green or red on the marking part or area confirms free and open or closed and occupied.
  • the invention also relates to an assembly of a door, a window or a panel equipped with a closing and/or locking mechanism and an operating device mounted thereto.
  • This figure shows a common closing and locking mechanism/door lock (16) meant to be fitted in an end face of a door, of which a sliding of latch bolt (21) in and out a door pin, can be operated by rotation of a connecting axle (not shown) that can be inserted/connected to number 22.
  • the mechanism has also a dead bolt (20) for locking the jamb of the door with a lock pin of a (toilet) locker, that can be operated by rotation of a connecting axle (not shown) that can be inserted/connected to number 23.
  • This figure shows a worm bushing (1) with a worm groove (13) matching starts of a worm (6) of a worm shaft (2).
  • a spring (7) is positioned in between.
  • a hole (15) - here a square - in the worm shaft (2) is to accommodate a connecting axle.
  • Number 14 is indicating a mutual axial direction.
  • Number 3 are splines of the worm bushing (1).
  • FIG. 14 This figure shows that the various parts are positioned in the axial direction (14).
  • the splines (3) of the worm bushing (1) are designed to slide in splines (4) of a body (5) and an end-stop (12) is shown.
  • a rotor (9) is mating the worm bushing (1) and is free of relative rotation and surfaces (25) of splines (18) are mating surfaces with teeth (19) of a pusher (8).
  • This figure shows a cross cut of the device in a top position, as is the worm bushing (1).
  • the splines (3) of the worm bushing (1) are slid within the splines (4) of the body (5).
  • the spring (7) is clearly positioned between the worm bushing (1) and worm shaft (2) and has decompressed, and the worm shaft (2) has a provision (24) for the spring (7).
  • Number 15 is the square hole in the worm shaft (2) to fit a connecting axle.
  • the worm bushing (1), the rotor (9) and the pusher (8) are relative positioned in axial direction.
  • the figure shows that the starts of the worm (6) are fitted in the worm grooves (13) of the worm bushing (1).
  • a pulling spring (10) is connecting to the pusher (8) and the worm bushing (1).
  • This figure shows a cross cut of the device in an inner blocking position, where the worm bushing (1) is blocked by the rotor (9), as the surfaces (25) of the splines (18) are blocked by blocking splines (28) of the body (5).
  • This figure shows a side cross cut where the rotor (9) and body (5) are shown separate, indicating the top position.
  • the splines (18) of the rotor (9) are slid into deep splines (17) of the body (5).
  • This figure demonstrates the movement (1 1) as a resultant of the slide of the inclined mating surfaces (25) of the splines (18) of the rotor (9), mating the inclined surfaces of the teeth (19) of the pusher (8), containing radial movement (29) and axial movement (30), as described in 7B, with arrows.
  • This figure shows a crosscut of further movement in axial direction towards the top position for the rotor (9) and the body (5), demonstrating a nearly achieved blocking position of the rotor (9), after further rotating and axial movement.
  • the surfaces (25) of the splines (18) of the rotor (9) slide along surfaces (27) of splines of the body (5), towards the blocking splines (28).
  • the rotor (9) will be held into blocking position and prevented for further axial and radial movement.
  • this figure shows the next stage as the pusher (8) is pushed and the mating rotor (9) is pushed out of the blocking splines (28).
  • This figure shows the device in inner position, such that only the top of the cover (36) is visible.
  • This figure shows a cross-section of an assembly and fitting of a base (34) to the body (5) with the use of clickers (33) and mating grooves (32). Also is shown a pin-hole connection between a pin (31) of the body (5) and a mating hole (26) of the base (34).
  • This figure shows the base (34) and extensions (38) to position the device relative to a closing and/or locking mechanism as to be fitted in rosettes or doorplates.
  • This figure shows a connection between the pusher (8) and the worm bushing (1).
  • the connection is fitted based on a bayonet catch (39).
  • This figures shows a configuration of a short version design.
  • FIG. 1 the common type of closing and/or locking mechanism is shown which has been given the reference numeral (16).
  • This mechanism (16) can be placed inside a suitable recess of a door.
  • An operating device as shown in fig. 4 and 5 can be fitted to the door at the location of either a connecting axle which has been placed inside the bushed lead- through (22) for operation of the latch bolt (21), either a connecting axle which has been placed inside the bushed lead-through (23) for operation of the dead bolt (20).
  • the operating device comprises a worm bushing (1) with a worm groove (13) to accommodate the start or starts of a worm (6) of a worm shaft (2) in a same mutual axial direction (14).
  • the worm shaft can be provided with the worm groove, while the worm bushing gets provided with the worm.
  • the relative axial and radial moves of the worm bushing (1) and worm shaft (2) as assembled are restricted, as the worm bushing (1) is restricted to rotate radial but free to move axial, and the worm shaft (2) is restricted to move axial, but free to move radial.
  • One possible configuration is to have splines (3) on the outer side of the worm bushing (1), mating with splines (4) of a body (5), so the worm bushing (1) can slide axial, and is prevented to move radial, relative to the body (5), and as the device is fitted to the door leaf, by means of the body (5), also relative to the closing and/or locking mechanism (16).
  • the worm shaft (2) has more than one start of the worm (6).
  • One of the favourable configurations of the device having 3 starts of the worm (6), as the forces in a triangle provides stability and spreads the forces.
  • the device can be assembled and configured as a complete unit, to be used for handles or toilet locks, and fitted as such a complete unit on the door leaf, while preferably at the same time getting actively connected to the latch or dead bolt via the respective connecting axle.
  • a compression spring (7) puts a load on the worm bushing (1) in the axial direction (14) relative to the worm shaft (2).
  • a rotor (9) and a pusher (8) grip into each other via a complementary toothing and thus are releasably connected in axial direction.
  • Splines (18) of the rotor (9) and teeth (19) of the pusher (8) are positioned in top position of deep unblocking splines (17) of the body (5).
  • the splines (3) of the worm bushing (1) are slidable through the splines (4) of the body (5).
  • the worm shaft (2) can be connected to the connecting axle in various manners.
  • One of the favourable alternatives is that the worm shaft (2) has a provision (15), like a profiled recess, to accommodate the mutual connection, like fitting around the complementary profiled connecting axle, like the square bar commonly used.
  • a rotation of the worm shaft (2) is able to drive the closing and/or locking mechanism and to thus either engage or disengage the closing and/or locking mechanism (16) by moving the latch bolt (21) or dead bolt (20).
  • the rotor (9) By pushing the pusher (8) inwardly, the rotor (9) is also pushed inwardly, as is the worm bushing (1). With this the spring (7) is compressed. During the inward movement, the spiral shape of the worm groove (13) inside the worm bushing (1) causes the worm shaft (2) to rotate around its central axis, and to thus operate the closing and/or locking mechanism (16).
  • decompression of the spring (7) is that no pulling action is required to drive the device in reverse, and so the manual operation of the device is limited to pushing actions.
  • One of the favourable springs is a compression spring (7) fitted in a centre of the worm bushing (1) and the worm shaft (2) as shown in figure 2, strong enough to drive the device and the closing and/or locking mechanism (16).
  • the worm shaft (2) has a provision (24), in this case a recess, in the worm shaft (2) to guide the spring and limit the movement in radial direction of the spring (7) during compressing and decompressing.
  • This position of the spring (7) has the benefit to create a relative stable movement and balance force between the worm bushing (1) and the worm shaft (2), and prevents the worm shaft (2) from moving relative in axial direction in relation to the door leaf during the decompression stage.
  • the operating device has two positions, both controlled by the position of the worm bushing (1).
  • One is the top position (figure 4) and the other is an inner blocked position (figure 5).
  • the worm bushing (1) In the inner blocked position, the worm bushing (1) is kept in an inner blocked position because of the rotor (9) being blocked by shallow blocking splines (28) of the body (5). See fig. 8. This provides blocking the worm bushing (1) in an inner blocked position relative to the worm shaft (2), and thus prevents it from returning fully back into the top position as was shown in figure 4, and therefore at the same time prevents the worm shaft (2) to fully rotate back in reverse. This inner blocked position is shown in figure 5.
  • the pusher (8) can be manually forced in axial direction towards the worm shaft (2), and the teeth (19) on the pusher (8) are then sliding axially inwards within the deep unblocking splines (17) of the body (5). These teeth (19) are pushing the splines (18) of the rotor (9), and the rotor (9) forces the worm bushing (1) into axial inward movement, and forcing the worm shaft (2) to rotate.
  • the signal to reduce the manual force on the pusher (8) towards the door leaf is either the circumstance that the pusher (8) is blocked for further movement in axial direction, or nearly bottomed out and a sudden reduction of back pressure is recorded, as soon as the splines (18) of the rotor (9) are fully slided out of the deep unblocking splines (17) of the body (5).
  • the rotor (9) rotates over a small angle (corresponding to the width of the splines (18) as an inclined surface (25) of the splines (18) of the rotor (9), slides along the teeth (19) of the pusher (8), and the rotor (9) moves along a path (1 1) both in the radial direction (29) and in the axial direction (30), as indicated in figure 7C, towards genuine position (figure 7B en 7C), forced by the decompressed spring (7) lifting the worm bushing (1) and the rotor (9) in the direction of the top position.
  • the spring (7) decompresses further, and pushes the worm bushing (1) and the rotor (9) in axial direction in the direction of the top position.
  • the inclined surfaces (25) of the splines (18) of the rotor (9) meet inclined surfaces (27) of the splines of the body (5) in axial direction, and drives the splines (18) of the rotor (9) into axial and radial movement (1 1) into the shallow blocking splines (28).
  • the blocked position can be released by a exerting a small inward push to the pusher (8) causing the worm bushing (1) to move inwards relative to the worm shaft (2) and relative towards the door leaf.
  • Pushing the pusher (8) the rotor (9) is forced with its splines (18) out of the shallow blocking splines (28), and no longer being restricted of radial movement.
  • the inclined surfaces (25) of the splines (18) of the rotor (9), slide along the teeth (19) of the pusher (8) and the rotor (9) moves into the axial and radial movement path towards genuine position (figure 7B en 7C).
  • the rotor (9) is no longer blocked with its splines (18) by the shallow blocking splines (28) but is now able again to enter the deep unblocking splines (17) therewith, and the spring (7) is free to decompress as no longer being held in position by the rotor (9).
  • the spring (7) now has the freedom to decompresses and move the device fully back into the top position while at the same time driving and rotating the connecting axle. It forces the worm bushing (1) away from the worm shaft (2) again and therefore drive the worm shaft (2) to rotate, which in turn causes the connecting axle to rotate. The closing and/or locking mechanism is then driven in reverse, and so are the latch bolt (21) or dead bolt (20). Thus the device is brought back into its top position (figure 4). If the device is used as a toilet lock, it is often necessary/desired that it can be operated from the outside, in case of emergencies. For this a provision is made to rotate the mutual connecting axle from the outside.
  • An extended part such as an indicator, provides to rotate the axle by a groove or similar to be applied for example by a screwdriver or a coin. Forcing the axle to rotate, the reverse action of the toilet locker can be achieved, and so disengagement between latch and jamb of the door.
  • One of the favourable configurations the device provides is the alternative method of releasing a locked position of the door, corresponding with the device as in figure 5. This is obtained by adding a constant small load in the axial direction (14) between the surfaces of the teeth (19) of the pusher (8) and the inclined surfaces (25) of the splines (18) of the rotor (9).
  • a favourable configuration is a spring (10) positioned between the pusher (8) and the worm bushing (1) to establish this small load. See figures 4 and 5.
  • this position can be changed in unlocked if, from the other side of the door, the mutual connecting axle of the closing and locking mechanism - which is connected to the worm shaft (2) - is rotated.
  • a small angle of rotation of about 15 centigrade's of the connecting axle and therefore of the worm shaft (2) suffices, and results in a pulling action of the worm shaft (2) relative to the worm bushing (1) as the starts of the worm (6) slide and so the worm bushing (1) moves axial towards the worm shaft (2).
  • the worm bushing (1) is connected to the pusher (8) by the additional connection like the pulling spring (10), the teeth (19) of the pusher (8) are forcing the splines (18) of the rotor (9) out of the shallow blocking splines (28) of the body (5).
  • the rotor (9) is now attached to the teeth (19) of the pusher (8) resulting in a
  • FIG 10 a variant is shown in which an indication or marking is provided on the pusher (8) or cover (36) of the pusher. This allows the user of the device to recognise whether the device is in the locked or unlocked mode. If the marking is positioned on an inner part (35) of the pusher (8) or cover (36), it will not be visible when the device is in the inner blocked position (figure 10B) but will be visible in the top position (figure 10A).
  • a colour such as white, green or red on the marking part or area as in figure (10A) confirms free and open or closed and occupied.
  • the device in an alternative configuration, as shown in figure 1 1 and 12, the device includes a base (34).
  • the base (34) is designed to be fitted in restricted positions with extensions (38) to have a good functioning operating device. This secures the assembly and functionality.
  • the preferred configuration is as the base (34) and body (5) are fitted together based on a fastening/clicking system. This means that the base (34) has clickers (33) and the body (5) has corresponding grooves (32) so that during the axial assembling, the clickers (33) bend slightly and then relax as soon as the clickers (33) match with the grooves (32).
  • the design of the clickers (33) and grooves (32) is focussed on blocking in the opposite axial direction thus preventing the loosening of the parts.
  • the body (5) and base (34) To block the assembled base (34) and body (5) for radial direction relative to the body (5), the body (5) and base (34) have a pin-hole (31 and 26) connection in axial direction.
  • a direct connection is provided between the worm bushing (1) and the pusher (8).
  • the connection is to establish that the position of the pusher (8) indicates in all times the position of the worm bushing (1). Pending of the way the device is fitted and positioned, in the inner blocked position, gravity or centrifugal force can slide the pusher (8) towards its top position (figure 4), as it can slide freely within the splines (17) of the body (5). This can confuse the user, and therefore a fitting by a connection based on for example a bayonet catch (39) to make visible at all times the position of the worm bushing (1), is preferred.
  • This connection also is able to guide the position of the decompression spring (7).
  • the rotor (9) is slightly different designed, such that it is no longer blocked in axial direction.
  • the worm bushing (1) has splines (3) to accommodate the splines (17) of the body such that it is no longer necessary that the movement of the worm bushing (1) in the axial direction (14) is taken place outside the splines (17, 28) of the body (5), and for that reason the total height of the device may advantageously result in a shorter version.
  • the splines (18) of the rotor (9) have a smaller diameter as the inner diameter of the body (5), such that the rotor (9) can rotate, as no longer being blocked by the splines of the body (17 and 28).
  • the splines (18) of the rotor (9) and the splines (3) of the worm bushing (1) slide within the deeper splines (40) of this shorter configuration back into the genuine top position.
  • the splines (3) of the worm bushing (1) in this configuration have a wider diameter as the splines (18) of the rotor (9) to accommodate the deeper splines of the body (40) and so be free to move axial, but restricted to move radial.
  • figure 14 demonstrates the rotor (9), with the splines (18) of the rotor.
  • the outer diameter of these splines (18) are related to the inner diameter of the body (5), such that the rotor (9) can rotate within the body (5).
  • the axial direction is indicated with 14, and for indicational means the worm shaft (2) is shown.
  • the shapes and/or dimensions of the various parts may differ.
  • another type of two-position switch mechanism can be used.
